Jerboas
Jerboas (from ar, جربوع ') are hopping desert rodents found throughout North Africa and Asia, and are members of the family Dipodidae. They tend to live in hot deserts. When chased, jerboas can run at up to . Some species are preyed on by little owls (''Athene noctua'') in central Asia. Most species of jerboas have excellent hearing that they use to avoid becoming the prey of nocturnal predators. The typical lifespan of a jerboa is around 6 years. Taxonomy Jerboas, as previously defined, were thought to be paraphyletic, with the jumping mice (Zapodidae) and birch mice (Sminthidae) also classified in the family Dipodidae. However, phylogenetic analysis split all three as distinct families, leaving just the jerboas in Dipodidae and revealing them to be a monophyletic group. Anatomy and body features Jerboas look somewhat like miniature kangaroos, and have some external similarities. Both have long hind legs, short forelegs, and long tails. Jerboas move around in a similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euchoreutinae
The long-eared jerboa (''Euchoreutes naso'') is a nocturnal mouse-like rodent with a long tail, long hind legs for jumping, and exceptionally large ears. It is distinct enough that authorities consider it to be the only member of both its genus, ''Euchoreutes'', and subfamily, Euchoreutinae. Long-eared jerboas are found in the Palearctic ecozone. The specific palearctic ecozone areas they are found in are southernmost Mongolia to the Takla-Makan Desert, Mengxin, Aerijin Mountain, and Qing-Zang Plateau regions of north western China. Long-eared jerboas in most cases are nocturnal, The long-eared jerboa's fur according to the book ''100 animals to see before they die'' "is reddish yellow to pale russet with white underparts." Very little is known about the species. Description The long-eared jerboa's head and body length measures to while its tail is double this size, between and . Like its disproportionately long tail, its hind feet are also large, helping it to jump high, me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allactaga Tetradactyla
The four-toed jerboa (''Allactaga tetradactyla'') is a rodent of the family Dipodidae and genus '' Allactaga'' that has four digits. It is the sole species in the subgenus ''Scarturus''. Four-toed jerboas are native to Egypt and Libya. They live in coastal salt marshes and dry deserts. Physical appearance Similar to the other jerboas in the genus '' Allactaga'', the four-toed jerboa are small hopping rodents with large ears and a long tail, with a black band near the white, feathery tip. The tail assists and serves as support when the jerboa is standing upright. They have long hind feet and short forelegs. The pelt of the four-toed jerboa is velvety in texture and the upper-parts are speckled black and orange, the rump orange, and the sides gray. The four-toed jerboa hind-limbs have an extra digit compared to other jerboas in the genus '' Allactaga''. The extra digit is smaller in size and nonfunctional compared to the other three digits. Nutrition Emerging at night, the four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zapodidae
Zapodidae, the jumping mice, is a family of mouse-like rodents in North America and China. Although mouse-like in general appearance, these rodents are distinguished by their elongated hind limbs, and, typically, by the presence of four pairs of cheek-teeth in each jaw. There are five toes to all the feet, but the first in the fore-feet is rudimentary, and furnished with a flat nail. The tail makes up about 60% of its body length and is used to gain balance while jumping. The cheeks have pouches. The Sichuan jumping "yeti" mouse (''Eozapus setchuanus'') from China can be identified by the ‘Y’ marking on its belly. Jumping mice live in wooded areas, grassy fields and alpine meadows. When disturbed, they start, in enormous bounds of eight or ten feet in length, which soon diminish to three or four, and in leaping the feet scarcely seem to touch the ground. They are nocturnal and generally live alone. The nest is placed in clefts of rocks, among timber, or in hollow trees, and ...

Sminthidae
Sminthidae is a family of mouse-like jumping rodents. They are represented by only one extant genus, ''Sicista'', represented by 19 species found throughout most of Eurasia, from central Europe east to Siberia, and south to southern China. However, they were much more diverse and had a much wider range in prehistoric times, having multiple genera and being found not only in Eurasia but also throughout North America, where they existed up to the early Pleistocene. They have a well-attested fossil record which dates as far back as the early Oligocene. They were formerly classified as the subfamily Sicistinae in the family Dipodidae alongside the jerboas and jumping mice, but phylogenetic evidence supports all three of these belonging to distinct families, thus leaving only the jerboas in Dipodidae.

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabbit
Rabbits, also known as bunnies or bunny rabbits, are small mammals in the family Leporidae (which also contains the hares) of the order Lagomorpha (which also contains the pikas). ''Oryctolagus cuniculus'' includes the European rabbit species and its descendants, the world's 305 breeds of domestic rabbit. ''Sylvilagus'' includes 13 wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit is, in many areas of the world, a part of daily life—as food, clothing, a companion, and a source of artistic inspiration. Although once considered rodents, lagomorphs like rabbits have been discovered to have diverged separately and earlier than their rodent cousins and have a number of traits rodents lack, like two extra incis ...

Mouse
A mouse ( : mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (''Mus musculus''). Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter. Mice are typically distinguished from rats by their size. Generally, when a muroid rodent is discovered, its common name includes the term ''mouse'' if it is smaller, or ''rat'' if it is larger. The common terms ''rat'' and ''mouse'' are not taxonomically specific. Typical mice are classified in the genus '' Mus'', but the term ''mouse'' is not confined to members of ''Mus'' and can also apply to species from other genera such as the deer mouse, ''Peromyscus''. Domestic mice sold as pets often differ substantially in size from the common house mouse. This is attributable to breeding a ...

Gerbillinae
Gerbillinae is one of the subfamilies of the rodent family Muridae and includes the gerbils, jirds, and sand rats. Once known as desert rats, the subfamily includes about 110 species of African, Indian, and Asian rodents, including sand rats and jirds, all of which are adapted to arid habitats. Most are primarily active during the day, making them diurnal (but some species, including the common household pet, exhibit crepuscular behavior), and almost all are omnivorous. The gerbil got its name as a diminutive form of "jerboa," an unrelated group of rodents occupying a similar ecological niche. Gerbils are typically between long, including the tail, which makes up about half of their total length. One species, the great gerbil (''Rhombomys opimus''), originally native to Turkmenistan, can grow to more than . The average adult gerbil weighs about . One species, the Mongolian gerbil ('' Meriones unguiculatus''), also known as the ''clawed jird'', is a gentle and hardy animal th ...
